To promote the structural features of the umbrella system, which consists of components such as umbrellas, parasols, handles, support poles, support poles, support poles, connections, etc., in which umbrellas, umbrellas, umbrellas, umbrellas, springs, caps, thin ropes, etc., are the three main components. The metal rod through which the poles are worn is connected to the end of the umbrella, and the switch is on the chain handle. The switch triggers the upward and downward movement of a metal bar, which, by operation of a line at the end of the umbrella, leads to the other parachute or tumble, or to the opening or binding of an umbrella, the spring of which is added to overcome the overstretch of the umbrella. The automated umbrella complex consists of mobile switches, wire ropes, upper and lower bearings, gears and transfer chains, installed in the umbrella pole. Installation of an axle bearing at the top and lower of the umbrella poles, with a wire-line ring around the two bearings, opening a "z" type moving switch at the appropriate position below the umbrella pole and connecting the steel line at its corresponding location with the steel line on top and down; a moving chain on one side of the steel line above the umbrella pole with a gear on each side of the pole at its corresponding location, with a gear gear that moves in tandem with a moving chain, and a reinforced umbrella support pole on each side of the gear。
To promote the difference between the two-fold umbrella and the three-fold umbrella of the umbrella plant,1 the structure is different, the two-fold umbrella can be broken, the two-fold umbrella structure is solid, durable, the barometer is used, the quality is excellent and it is easy to carry. Triple umbrellas can be folded and spread widely, as is usually the case for most umbrellas and parasols. Good quality, longer useful life, better sunscreen, medium weight and medium length. The whole is moderate and more popular. Two, two-fold umbrellas, which are essentially european umbrellas, are characterized by a variety of styles, generally covering only the sun, which cannot be used in rain, and larger; three-fold umbrellas, which are professional european umbrellas and also have a small barley umbrella, are the dominant style in the current market, characterized by ease of folding, recent popular pencil umbrellas, pen umbrellas, steel pen umbrellas, light umbrellas; and, as a general rule, most of the two-fold umbrellas are more obscurantistic, well-worked, dominated by embroidered, laced, embroidery, stamped umbrellas, and overpriced. The three-sum umbrellas are long, mostly umbrellas, with a wide range of options and relatively low prices. The two-fold umbrella, which is the fracture of the dragon bones (bones) holding the umbrella, means that the umbrella skeleton can be broken into two sections. And that's the idea of a three-block umbrella, which means three knots. 4. The two-fold umbrella combines the wind-proof function of the long-stamped umbrella and is better carried than the long-stamped umbrella, with many manufacturers developing a two-fold umbrella as an umbrella or an umbrella against rain. The weakness of the 20% umbrella is that when it is closed, the umbrella remains torn apart。
Propaganda that the umbrella plant's solar umbrella is in fact a replica of the umbrella is different from the traditional umbrella in that it uses the fabric of the uv umbrella. The general umbrella, on the other hand, uses common waterproof fabric. Therefore, the determination of whether the umbrella can be used as an umbrella is based on the fabric of the umbrella. Currently, the vast majority of solar umbrellas are used as umbrellas. Among the many fabrics, fabrics with thick umbrellas are better than thin uv-resistant, and generally cotton, silk, nylon, glue, etc. Are less uv-resistant and better uv-protected; therefore, most solar umbrellas are mainly made of detergent fabric, which is also made of ordinary umbrellas. So most solar umbrellas are used as umbrellas。
Propaganda umbrella plant black tape is better in there than out there, it's good in there one, it's dark, it's light. Most of this light is reflected and the rest is absorbed by the dark of the inner layer. 2. If black is outside or on both sides, it is hot and hot because most light is absorbed. If black is out there, black absorbs all color light, so it's black, so if black is out, all color light is absorbed, so it's particularly hot. 3 and the gel layer is fragile and, if placed on the outer layer, generally scratching and rain water has a corrosive effect on sunscreen coatings, which can be reduced over a long period of time, thus affecting sunscreening. So it's better to choose the product in it。
